Work Queue Length /Peak /Limit

These numbers refer to a queue of server requests that are waiting for the use of a native thread from the pool. The Work Queue Length is the current number of requests waiting for a native thread, which is represented as Requests Queued in the Admin Console.

Peak indicates peak requests queued in the Admin Console and is the highest number of requests that were ever queued up simultaneously for the use of a native thread since the server was started. This value can be viewed as the maximum concurrency for requests requiring a native thread.

Limit is the maximum number of requests that can be queued at one time to wait for a native thread, and is determined by the setting of NativePoolQueueSize.


You can modify the queue size for NativePool by editing the NativePoolQueueSize directive in magnus.conf. For more information, see NativePoolQueueSize Directive.
